From the Polizei NRW press portal: Schutzschuhe für Düsseldorfer Polizeidiensthunde.
Mainly as a protection against shards of glass, the dog squadron of the Düsseldorf police force has purchased 20 sets of commercially available protective shoes for their four-legged colleagues.
Apparently there's a problem in Düsseldorf with beer bottles being discarded on the pebbled walkways of the Altstadt.
The dogs are currently on patrolling safe ground so as to get accustomed to the shoes. In a few weeks time they'll be used for real around the city center and at events such as football matches.
